How to Find Companies Approaching the Audit Threshold

By the time a growing company starts looking for its first auditor, it’s often already speaking to your competitors. The opportunity for audit firms is to spot the signs earlier: a second year of growth, a new acquisition, or an expanding finance team. Each could point to a business whose audit needs are changing, and a reason to start a conversation now.

The challenge is finding those companies systematically. A list of businesses with turnover close to £15m is a starting point, but on its own it can’t tell you who needs an audit, or when. Beauhurst tracks over 7k companies with the latest turnover between £10m and £15m, with a total turnover of £75.0b.

Here’s how to build an audit pipeline around the thresholds, the two-year rule, and the wider signs of a business preparing for greater scrutiny.

The UK audit thresholds

For financial years beginning on or after 6 April 2025, a private company may qualify as small if it meets at least two of these three conditions:

• Annual turnover of no more than £15m
• Balance sheet total of no more than £7.5m
• An average of no more than 50 employees

Small companies are generally eligible for audit exemption, subject to the rules for groups and certain types of company. The turnover and balance sheet limits increased from £10.2m and £5.1m respectively; the employee limit stayed at 50. GOV.UK’s audit exemption guidance sets out the current conditions.

That two-of-three test matters for prospecting. A business with £16m in turnover doesn’t automatically need a statutory audit if it remains within both the balance sheet and employee limits. Equally, a company below £15m in turnover may cease to qualify as small because it exceeds the other two limits.

The timing needs care, too. A change in size generally affects a company’s classification when it meets, or ceases to meet, the relevant conditions for two consecutive financial years. In practice, a small company that exceeds the limits for the first time usually keeps its small status for that year, which gives audit firms a natural window to start the conversation. For the first financial year beginning on or after 6 April 2025, the higher thresholds can also be applied to the previous year when running that test. Treat an apparent threshold crossing as a prompt to investigate.

Which companies actually need an audit?

The most obvious prospects are companies growing beyond the small-company limits. A search also needs to catch the circumstances a turnover filter misses.

Group structure is one. A subsidiary’s position cannot always be judged from its standalone figures. The size and eligibility of the wider group, along with any applicable subsidiary exemption, need to be checked. An acquisition or new holding company can therefore be significant even if an individual company’s latest accounts look modest.

Some companies are ineligible for small-company audit exemption because of their status or activities. These include public companies and certain banking, insurance, and investment businesses. Eligibility should be checked against the current rules before an outreach team describes a company as exempt or audit-required.

There is also demand beyond statutory audit. A company may choose an audit, or be asked for one by a lender, investor, or shareholder, even when it qualifies for an exemption. Shareholders holding at least 10% of the shares can also require one. For some prospects, the more relevant question is: What assurance do the people around this business need?

Limited liability partnerships (LLPs) have parallel size thresholds, although their requirements should be assessed under the LLP rules rather than assumed to be identical to those for companies.

Signals that a company is approaching the audit threshold

Filed accounts provide an important baseline, but they don’t always give the whole picture. Smaller companies may file accounts without publicly disclosing turnover. Financial figures can also lag behind what is happening in the business today. That makes it useful to combine accounts with more recent growth and company events.

Financial growth

Look for companies whose disclosed turnover, balance sheet total, or employee numbers are moving towards the limits over successive years. Pay attention to the combination of measures: two indicators rising together are more relevant to the size test than turnover alone.

Where a figure is unavailable in public filings, record it as unknown. A missing turnover figure isn’t evidence that a company sits below the threshold.

Funding, acquisitions, and group changes

A funding round may support hiring and expansion. An acquisition can change group size or reporting requirements. A restructure may create new subsidiaries or alter where financial decisions are made.

None of these events proves that an audit is due. They do, however, give an audit team a good reason to review the company’s accounts and ownership structure.

Changes in financial leadership

The appointment of a chief financial officer (CFO), finance director, or experienced non-executive director can signal that a business is strengthening its financial oversight. It also gives you a natural point of contact for a conversation about reporting processes and audit readiness.

New lending

A newly registered charge can prompt a closer look at the company’s financing arrangements. A charge alone won’t tell you a lender wants an audit, but alongside growth, refinancing, or a change in ownership, it strengthens the case for a conversation.

The strongest prospects usually show several signals together. A company growing its headcount, acquiring a business, and appointing a finance director is more useful to investigate than one that simply appears in a broad £10m to £15m turnover search. Out of the 7.43k companies that sit in the £10-15m band, there were 41 funding rounds in that past 12 months, equating to £413m of investment. 

How to build an audit-threshold pipeline

Step one: Define the clients your firm can serve well

Start with your sector strengths, geography, preferred company size, and capacity. Decide whether the pipeline should cover first-time statutory audits, voluntary audits, group work, or a combination. This gives the research team a clear basis for prioritising prospects.

Step two: Build an initial company universe

Search for businesses approaching the relevant size limits. A £10m to £15m turnover band can be a useful starting point where turnover data is available, but include searches based on assets and employees so the pipeline is not shaped by one measure alone.

Keep companies with missing public financial data in view when other signals suggest they may be relevant.

Step three: Review the trajectory, not just the latest figure

Compare available accounts across multiple years. Is the business growing consistently, fluctuating around a limit, or moving back below it? Check when each accounting period began so you apply the appropriate thresholds.

At this stage, the aim is to identify companies worth assessing, not to declare that they have crossed the statutory audit threshold.

Step four: Check timing and group structure

Review the two-year rule, any relevant transitional treatment, and the company’s position within a wider group. Look for recent acquisitions or restructures that may have changed the picture since the last accounts were filed.

This step is where a promising lead becomes a more credible opportunity for a partner to review.

Step five: Find the right person and reason to speak

Identify the finance director, CFO, founder, or other relevant decision-maker. Give the partner a short account of why this company is on the list: its growth, a recent event, what is known from the accounts, and what remains to be confirmed.

A useful pipeline entry gives the partner enough to hold an informed conversation.

Step six: Monitor for change

Save the target group and revisit it when accounts are filed or other significant events occur. Update the opportunity stage and next action as new information comes in. Done this way, threshold research becomes a repeatable part of business development.

How to approach a potential first-time audit client

The best opening is specific to the company and honest about what you know. An initial approach might mention its expansion or acquisition and offer a discussion about the reporting and assurance questions that often accompany that change.

Avoid telling a prospect that it will need an audit based on an estimated turnover figure or one year of growth. Instead, offer to help assess its position and prepare if an audit becomes necessary.

That preparation can have value well before an auditor is appointed. A first-time audit conversation may cover the quality of financial records, documentation, controls, group reporting, and the demands an audit could place on the finance team. For a company considering a voluntary audit, the discussion may begin with what its lenders, investors, or shareholders need from the accounts.

Where your firm has an existing relationship with a founder, investor, or adviser, ask for an introduction. Otherwise, a direct approach works when it’s grounded in a specific company event and a clear reason for making contact.

Common mistakes to avoid

An audit-threshold pipeline can lose its value if every company near £15m is treated as an imminent mandate. Watch for these recurring issues:

• Using turnover as the only test. The small-company assessment considers three measures and generally requires two to be exceeded before size alone removes the exemption.
• Treating one year as conclusive. Check the two-year rule and the transition to the thresholds introduced in April 2025.
• Ignoring groups. A subsidiary’s standalone accounts may not establish its audit position.
• Assuming missing figures mean low figures. Publicly filed accounts may omit information your team would ideally like to search.
• Overlooking voluntary demand. Audit and assurance conversations can arise from lender, investor, or shareholder needs.
• Forgetting clients moving the other way. The April 2025 increase took many companies out of statutory audit. Existing clients in that position may still want an audit, a review, or other support, and competitors will be asking them.

These checks should sit between the initial search and any partner outreach. They make the resulting pipeline smaller and far more useful.

How BeauhurstAdvise can help

Building this process manually means moving between filings, ownership records, company news, and contact research. BeauhurstAdvise brings company financials, ownership information, deal history, and people data together so audit and accountancy teams can research and prioritise opportunities in one place.

Teams can use searches to identify companies that fit their target profile, examine available historical financial information, review corporate structures, and save relevant businesses for monitoring. Funding, acquisition, and leadership information can add context before a partner makes contact. Personalised alerts using Beauhurst Collections help the team revisit companies as their circumstances change.

Beauhurst data provides a stronger starting point for professional judgement. It does not replace a review of the accounts and applicable audit rules, particularly where filed figures are incomplete or group eligibility is complex.

The result is a more practical audit pipeline: named companies, a reason each one matters, the people to speak to, and a clear next step.

Finding the opportunity before the formal requirement

The audit threshold is useful for defining a search, but a good pipeline is built around movement towards a need. Accounts show part of that movement; funding, acquisitions, new lending, and leadership changes fill in the rest. And because the two-year rule usually gives a growing company one year over the limits before it loses small status, that year is the window to be talking to it.

For audit firms, the opportunity is to bring those signals together, check them carefully, and start conversations while there is still time for the company to prepare. Explore BeauhurstAdvise to see how company data can support that process.
